Objective: To compare volatile organic compounds in nine samples including three blank packaging materials(composite membrane of polyethylene and aluminum foil

polyethylene plastic membrane

leather condensate membrane paper)

these three kinds of materials have packaged and Lycium barbarum pieces have packaged for 12 months using these three kinds of packaged materials. Method: Component analysis of volatile organic compounds in these nine samples was determined by head-space gas chromatography

the relative content of each compound was gained by area normalization method. Result: Vvolatile organic compounds in each sample were mainly oxidation terpenoids

aldoketones and fatty acids compounds

among them

blank polyethylene bag peculiarly included volatile dissolvent(ethanol and acetone);Isopropyl alcohol and n-pentanol were only being in leather condensate membrane paper;polyethylene bag and leather condensate membrane paper which packaged L. barbarum pieces for 12 months all contained benzaldehyde.Three blank packaging material all contained BHT which was additive antioxidant usually used in plastic packaging materials

only blank leather condensate membrane bag contained BHA which was additive antioxidant usually used in plastic packaging materials;furfuraldehyde was the main ingredient in L. barbarum which packaged for 12 months. Conclusion: Compositions and relative content of L. barbarum pieces using different packing materials were different

it showed that packaging materials had an important effect on volatile organic compounds in the pieces.
